Yorky, that might be because if her hair is like mine, after using a shampoo for a while the hair decides it no longer likes it. I have four I rotate, depending on how my hair is getting along with the shampoo. I've also relegated a couple to cleaning duty. Did you know that shampoo cleans soap scum off fiberglass shower walls and tubs? Just be sure to rinse thoroughly!
